A.4.4 Reset Reason 0013 Fault Analysis
The following example shows the content of the SYSFLT and SYSADR registers
after a Reset Halt. The following paragraph analyzes the register content and
identifies the faulty FRU.

The SYSFLT register indicates a NXIO (nonexistent I/O) error. The SYSADR
register contains a 30-bit address of 399F0000. However, after sign extended to
32 bits the address is translated to F99F0000.
Figure A–4 shows that F99F0000 is the address of an interface module in Zone
B, slot 17. The module failed to respond to its address causing a bus timeout.
Replace the module.
